Objective: To estimate the incidence of different shapes of the medial and lateral meniscus and the incidence of discoid meniscus in the South Indian population. Methods: The study included 108 menisci from 54 adult cadaveric knee joints which were preserved in 10% formaldehyde solution. After the dissection procedure, the morphological variants of the shapes of menisci were macroscopically noted and classified. The medial meniscus was subgrouped as crescent-shaped, sided U shaped, sided V-shaped, sickle- shaped and C-shaped. The lateral meniscus was subgrouped as crescent-shaped, C-shaped and discoid-shaped. Results and Conclusion: From our observations, 50% of the medial menisci were cresent- shaped, 38.9% were sided V-shaped and 11.1% were sided U-shaped. The percentages of the different types of lateral menisci were 61.1%, C-shaped and 38.9%, crescent-shaped. No discoid medial or lateral meniscus (0%) was observed in the study.
